STOCK-SHELL FOB WINDING FABRICS.

7 '0 all whom it may concern:

Be it known that I, WViLLIAM F. Ga van:- Tnn, citizen of the UnitedStates, residing at Cadiz, in the county of Harrison and State of Ohio,have invented certain new and useful Im Jrovements in Stock-Shells forWinding Fabrics, of which the following 18 a specification.

My invention relates to winding shells or rolls such as are used in themanufacture of those fabrics which are worked hot and which arecalendered, the improved winding shell devised by me being particularlya plicable for the manufacture of sheet rinber and being used inconnection with the calendars or rolls which form the rubber compoundinto'sheets. These sheets are run out upon the fabric and the fabriccarrying this newly formed sheet is wound upon a roll to facilitatehandling and feeding the sheet rubber into the various machines throughwhich it passes in the process of manufacture.

This invention is an improvement uaon the stock shell illustrated anddescribe in by )rior Patent, Number 1,003,593 of Sep-.

tom or 19, 1911, and the improvement particularly relates to the head ofthe shell.

One object of my invention is to so construct the head that the sheetmetal shell will not be broken or damaged-by the insertion of the squareiron mandrel into the shell. In the form of my invention illustrated inthe patent before referred to, a square tube is shown passing throughthe mandrel concentrically to its axis and disposed on the inside of thehead. It has been found in practice that in using this form of shell,the workmen would insert the square iron mandrel into the tube an inchor two and pry the loaded shell around breakiru the tube downsufficiently to expose the tai piece of castings so that when themandrel was being put clear through the shell the mandrel would knockthe head out. It is to avoid this objection that I have devised thepresent form of head for the shell and the manner of connecting thecentral tube to this head.

A further object of the invention is to strengthen the tube and soconstruct it that it will distribute the strain along the entire lengthof the tube when the shell is in use.

My invention is illustrated in the accompanying drawings wherein:

view of a shell constructed in accordance Fig. 2 is a perspective viewof one of the heads of the shell looking at the inside thereof. Fig. 3is a longitudi nal diametrical section of the shell and head. Fig. 4 isa reduced cross section on the line 4-4 of Fig. 3.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

Referring to these drawings, 2 designates an ordinary shaft or mandrelsquare in section at its middle portion, this shaft or mandrel beingcylindrical at its ends. Shafts or mandrels of this character areusually used for the purpose of supporting and rotating windin rolls ofthis nature. in order not to obscure the drawing this shaft or mandrelis illustrated in dotted lines in Fi 1 onl ounted upon the shaft 2 isthe stock shell. This stock shell consists of a cylinder of thin metaldesi nated 3 and o )posed heads 4 supporting t e ends of the cy inder.

One of these heads 4 is illustrated in Fig. 2.

Each head comprises a disk-like portion 5 having acircumferentialoutwardly extend ing flange 6. The face of this flangefor a 1,

portion of its width is cut awa as at 7 so as to leave an outwardlyprojecting shoulder 8 at the extremity of the flange. This cutawayportion has a proximately the thickness of the metal cylinder 3. Thecenter of each head 4 is formed with a s uare aperture 0 and the metalof the head around this square aperture is formed to provide the inwardly proiecting walls 10 as illustrated clearly in big. 2. There aretwo of these walls 10 diametrically opposite to each other, each of thewalls being angular in form so as to extend along two sides of thesquare aperture. At the junction between the walls 10, the walls are se)arated from each other as at 11, the edges 0 the walls divergingslightly outward. The body of each head is formed with a plurality ofventilating perforations 12. The metal cylinder 3 is held to each of theheads by means of rivets 13 which are countersunk in the metal of thecylinder so as not tointerfere with the proper winding of the fabricthereon. The intermediate portion of the shell is reinforced by one ormore rings 14 to which the shell may be riveted.

Mounted upon the fian es or walls 10 and extending from one hea to theother and ill) forming a central guiding passage through which themandre 2 ma be placed and guided in position, is the s eet metal casingor tube 15. This tube as illustrated in Figs. 1 and 4 is square in formand has the same cross sectional area as the area of the opening 9. Thetube 15 is formed of two pieces of sheet metal each of a length adaptedto extend from one head to the other, each piece being angularly bentlongitudinally.

The margins 17 of each of the sheet metal sections 16 is outwardly bentand the marginal edges of one section 16 lie against and confront themarginal edges of the other section 16. These sections 16 are held toeach other by means of rivets or in any other suitable manner.

The completed tube 15 is adapted to be inserted at its ends within thewalls 10 with the projecting margins 17 projecting throu h the clefts orspaces 11 as illustrated clear y in Fig. 4, the ends of the tubeabutting solidly against the margin of the opening 9, the flanges 10being spaced sli htly from the wall of the opening to provi e thismargin or shoulder. In my former patent this tube was formed of onepiece of sheet metal, square in cross section, and was adapted to fitover walls corresponding to the walls 10. There was no way of fasteningthis tube in place and, furthermore, inasmuch as the tube passed overthe walls corresponding to the walls 10, the ends of the walls formedledges which would be struck by the mandrel when inserting it and thiswould tend to dama e the shell. By my present invention the tu 15extends into and forms a linin for the walls 10 of each head and the tue therefore extends from end to end of the stock shell so that there isno projection on the inside of the tube against which the mandrel willstrike. Furthermore, by forming the tube with the flanges 17 andinserting these flanges in the slots or clefts 11, the-tube is veryrigidly connected with the head so that the head and'tube will rotate toether and rotational strain will be transmitted from one head to the oposite head, not only by means of the shell but by means of the centraltube.

With this new construction the ends of the tube enter the heads of theshell and as a consequence the mandrel when inserted and pried aroundcan not spread the tube. Furthcrmore, this tube forms a passage for themandrel of uniform diameter throughout its length so that when insertingthe mandrel it is impossible to knock the heads out or weaken the heads.Furthermore, inasmuch as the flanges 17 of the tube are. securely heldin the slots of the tail piece,any strain at onone head is transmittedto the other read most efi'ectually.- I

While it forms no part of mypresent invention and is clearly describedand claimed the fa ,der it. A com lete rotation of the shell in myoriginal patent before referred to, it may be explained that thecylinder 3 does not extend entirely around the shell but that the edgesof the cylinder 3 are spaced from each other as at 18. The margins ofthe sheet are, however, connected by a bridging late 19 which is rivetedor otherwise attached at its edges to the margins of the sheet metal 3.

The apron 20 is formed of canvas, duck or other suitable fabric and isdetachably connected to the shell. To this end, the apron at one end isprovided with a longitudinally extending pocket or hem into which ametallic strip 21 is inserted. In order to attach the apron to the roll,it is only necessary to insert the metal strip 21 into the hem at theedge of the apron and insert the edge of the apron and. strip into theslot 18. This metallic strip is, of course, wider than the slot 18 sothat after it. is inserted from the end of the shell it can not beremoved except by withdrawing it longitudinally. The object of thisapron is to clamp or bind the sheet of compound and fabric upon the rollor shell so that it may be easily wound thereon. In starting to wind thesheet of fabric and the new sheet of rubber u on the roll, the apron israised and brie carrying the rubber is started uncauses the fabric toclose down u on the .apron and the apron bein anchore to the shell,binds the end of the abric and the rubber closely to the shell.

In use, the roll is placed upon the man- ,drel or shaft and the shaftconnected to any means for rotating it. The roll is rotated "and thestock is wrapped thereon, one convolution upon the other until thedesired amount of stock has been received upon the roll. After theproper amount of stock has been rolled upon a given roll, the shaft maybe removed and placed in any desired position. The objectof providingperforations in the heads 4 is to ermit the heat conducted to the shellto e ra idly dissipated. It will be seen that this a sorption of theheat of the stock by the roll is aided by the fact that the cylinder 3is of thin sheet metal so that the heat is readily communis cated to theair inside of the roll and this air will be constantly changed by meansof the ventilating openings in the heads.

The object of forming the shell of metal rather than wood, as was thepractice prior to my patent before referred to, is to not only dissi atethe heat but provide a roll which wil carry off the frictionalelectricit enerated by the friction of milling or rol mg the rubber intosheets. As this is fully described in my prior patent, there is no needof a more extended reference here.

What I claim is:

" 1. A stock roll for winding sheets of hot material including a hollowcylindrical shell of relatively thin metal, end pieces or heads carriedwithin the ends of the shell, each head comprising a body portion havinga peripheral flange supporting the shell and having a central, manysided aperture, said aperture having inwardly extending Walls and saidwalls being longitudinally slotted, and a central tube extending throughthe cylinder and attached to said end pieces and having flangesextending radially through the slots of the head.
